I'm moving this message over to bacula-devel which is more appropriate for discussing the changes.

You probably need to get a decent debug log from the SD to get a good idea as to what the problem is (-d 200 is probably ok). The log snippet that you posted suggested that it was trying to write to the DVD when it failed. That is probably too late to catch the error and fail gracefully and any fix is likely to be needed in the mount code. The place to start is probably in src/stored/mount.c the mount_next_write_volume function is what will fail gracefully and ask the sysop to mount a new volume (look for dir_ask_sysop_to_mount_volume(dcr) around line 89 and line 161). I think that it will be try_autolabel that actually fails when there is no DVD. Basically I suggest that you get the SD debug log and look for any messages from mount_next_write_volume and try_autolabel. Another thing to look for is a call to the freespace command. That is probably a good place to hook into if no disk is present. As for the fix I suspect that dvd-handler needs to be modified to return a well known error code/string from the freespace command. Then the bit around mount/autolabel needs modifying to not let bacula start writing/labelling a volume if no disk is present.
